Comparison of blind intubation with different supraglottic airway devices by inexperienced physicians in several airway scenarios: a manikin study

Bielski A, Smereka J, Madziala M, Golik D, Szarpak L. Eur J Pediatr. 2019 Jun;178(6):871-882

This manikin study aimed to compare the performance of several supraglottic airway devices (SADs) in different blind intubation scenarios performed by 116 inexperienced physicians. The devices used included i-gel, Air-Q laryngeal airway and Ambu AuraGain. The three devices were tested on a paediatric manikin in three different scenarios, which included normal airway without chest compressions (A), normal airway with continuous chest compressions plus the CORPLUS CPR system (CCS) (B), and difficult airway with continuous chest compressions plus CCS (C). Parameters assessed in this investigation included first intubation success rate, median time to SAD placement, time to endotracheal intubation, as well as ease of intubation. Results have shown that the i-gel performed better in every scenario and in all parameters tested as compared to the other devices. Therefore, these data demonstrated that the i-gel is the most effective device for emergency blind intubation performed by inexperienced physicians in paediatric patients.

How do different brands of size 1 laryngeal mask airway compare with face mask ventilation in a dedicated laryngeal mask airway teaching manikin?

Tracy MB, Priyadarshi A, Goel D, Lowe K, Huvanandana J, Hinder M. Arch Dis Child Fetal Neonatal Ed. 2018 May;103(3)

This manikin study assessed and compared the delivered ventilation of seven, size 1 LMA devices with two different face masks using self-inflating bags (SIBs). 40 participants carried out resuscitation on a specialised infant training manikin using the LMAs and the face masks in a random fashion. Findings have shown that the i-gel had the highest peak inspiratory pressure and higher PEEP compared to the other devices. In addition, the i-gel showed no insertion failures and all users described it as easy to use. Thus, these results indicate that the i-gel may become the primary resuscitation device used for newborn resuscitation.

Are nurses able to perform blind intubation? Randomized comparison of I-gel and laryngeal mask airway

Ladny JR, Bielski K, Szarpak L, Cieciel M, Konski R, Smereka J. Am J Emerg Med. 2017 May; 35(5): 786-787

Manikin study to assess effectiveness of blind intubation through the i-gel, LMA Classic and a standard cuffed tracheal tube, performed by 34 nurses in CPR conditions across two scenarios (with and without chest compressions). Primary measure was time to intubation. i-gel recorded a lower median time to intubation and higher, statistically significant, successful insertion rates in both scenarios. Performing compressions doesn't significantly affect time to perform blind intubation in this setting, but reduces the effectiveness of first intubation attempt. i-gel was faster in both scenarios.

Comparison of the Macintosh laryngoscope and blind intubation via the iGEL for intubation with cervical spine immobilization: A randomized, crossover, manikin trial

Gawlowski P, Smereka J, Madziala M, Szarpak L, Frass M, Robak O. Am J Emerg Med. 2017 Mar; 35(3): 484-487.

Paramedics performed standard intubation and blind intubation in three airway scenarios. Results show that blind intubation with the i-gel was superior to ETI performed by paramedics.

Competence in the use of supraglottic airways by Australian surf lifesavers for cardiac arrest ventilation in a manikin

Holbery-Morgan L, Angel C, Murphy M, Carew J, Douglas F, Murphy R, Hood N, Rechtman A, Scarff C, Simpson N, Stewardson A, Steinfort D, Radford S, Douglas N, Johnson D. Emerg Med Australas. 2017 Feb;29(1):63-68

Lifesavers in Australia who already use pocket masks and BVMs were trained to use the LMA and i-gel on a manikin. Time to effective ventilation was similar between the pocket mask, BVM and i-gel, but longer for LMA. Authors feel there is a limited role for supraglottic airway devices in this scenario.
